The Transport of Photosynthetic Products from the Chloroplasts of Tobacco Leaves

Abstract
Tobacco leaves were fractionated by the non-aqueous method after photesynthesis for short periods in 14CO2 and with or without subsequent photosynthesis in 12CO2 or respiration in the dark. Phosphate esters became labelled only slowly in the non-chloroplast parts of the leaf; glycine and serine which became rapidly labelled in the non-chloroplast leaf fraction appear to be concerned in the transport of newly assimilated carbon from the chloroplast.
